[Objective] In order to reduce the damages of conventional grilled dam caused by debris flow
a novel debris dam with friction damper is proposed. [Methods] Simulating of massive stone in debris flow by steel ball
the finite element software ABAQUS was used to simulate the dynamic responses of the impact of large stones. [Results] As compared with the ordinary grilled dam
the stress response of beam-column joints was obviously reduced when an impacting force was applied against the dam. [Conclusion] The damped dam had well impact-resistance performance either in displacement withstanding or in energy reduction.
